Benefits & Use Cases
This smart lock is especially beneficial for households with children or elderly members who may benefit from quick, key-free access, as well as busy professionals who want peace of mind when leaving the house. Property managers handling multiple rentals will appreciate the ability to assign individual codes and monitor access logs remotely. The automatic locking feature reduces human error, making it ideal for those who frequently forget to lock their doors. Voice control adds accessibility for individuals with mobility challenges or those preferring hands-free operation. Whether installed on a main entry door or interior bedroom door, the sleek silver finish complements modern interiors while delivering reliable performance.
Important Notes
The lock does not include a built-in gateway, so voice control functionality requires an additional gateway device that must be purchased separately. Installation is straightforward but assumes basic DIY capability; no professional tools or wiring are involved. While the build quality has been praised for functionality and value, some users note variability in perceived durability. Always ensure your door’s thickness and backset align with standard specifications before purchasing. The package includes the lock unit, mounting hardware, and installation guide—no additional components are provided beyond what’s necessary for typical setup.

Exactly what I wanted
I bought three for my house and I couldn’t be happier with the purchase. It was delivered on-time and in a well-packaged box. Installing them went smoothly, although you should know that you should put your existing deadbolt below this lock, which takes a little bit extra time. Once installed, it took me only a few minutes to download the app and gain control of my lock. You can generate codes quickly, however, it creates randomized codes. To set the code to what you want, you first need to unlock the door with the new code, then you can change the code to what you want it on your app. It would be nice if you could just create new codes that you choose right away, but it’s a small inconvenience and only needs to be done once. It’s nice that you can name codes so it’s easy to identify who unlocked the door rather than having to remember whose unique code it was. Setting a custom finger print is also easy (it only takes 4 samples of your finger to setup) and works well. The door locks instantly after entering your code or using your fingerprint. Once you have all the custom codes that you want in one lock, you can import them into other locks with a couple clicks. You cannot import custom fingerprints (to my knowledge). Again, a minor inconvenience that you only need to do once.To summarize:Pros:-Slick and durable door handle-User friendly app with fast setup-Lots of different entry options to fit your needCons (no major concerns):-Deadbolt needs to go below this doorhandle-To create custom codes, you first need to enter the new randomized code before editing the code-No import for fingerprintsIf I ever need a new set of door locks, I would have zero hesitation purchasing these again.

Setup
Was difficult to install even after watching YouTube & the provided installation video. Finally called and gentleman was very nice. He explained and sent pics to make it easier to install. Works great so far. Itâs sturdy, looks nice, fingerprint sensor is very sensitive. Do mist times have to use 2-3 times before the door unlocks.

best door handle i ever had
I’ve had several different door locks on amazon, normally the cheapest, they all lasted, never had an issue once, however this one is more secure and the most solid feeling door handle ever, feels like its a 500 door handle and looks like one too, everyone comments on it. Finger print buttons all of it works flawlessly and super easy to set up, no problem anyone can do it in less than an hour install and set up. Ill post a pick later, it makes any door look expensive

Seems to be well built
The unit seems to be well built. The online installation directions are slightly different than the paper directions. It is nice to have multiple ways to unlock the door. I am thinking our favorite, because of convenience, is the fingerprint method. The method is a bit finicky so far, but this could be because we didnât get a thorough coverage when training on or prints.The jury on the battery life is still out. We just got the unit a few days ago. So far so good.A separate gateway is needed to use, WiFi connection. I probably should have read closer.

Love it!!
I live next to bad people who have threatened my life so to help me feel safe at home when my boyfriend isnât home we got new door nobs. I was able to install them by myself thanks to the help of the videos to fallow along with and programming them was just as easy! They are working great! Itâs nice to know that I have full control over who is able to come into my house and I can see who came in on what day and time. I love the different options so our friends and family can choose between fingerprint, code, or the cards for whatâs best for them. Iâm also able to control it from anywhere and set up a temporary code for a specific time frame if needed. Hopefully we donât have any problems with them. Because I just want to feel safe when Iâm home alone again.

This smart lock has so many features and ways to open. It has fingerprint reader, passcode for you and to sent to people you wanna let in without being at home, key fobs, you can use the app to open the door and also 5 sets of keys, just in case. It looks super classy, heavy, great materials and super easy to install.

Works Flawlessly!
This makes opening our doors a breeze. Quality is excellent and installation was super easy. We ended up purchasing more of them for multiple locations. They look high end.

It works
It is pretty sturdy. A pain in the butt to put together. The fingerprint reader works, but not very well when it’s raining. The keyhole hider is pain, the things comes fly off when I don’t want it off and is a pain to open when I do. You can customize codes to person, only it doesn’t work right away. If you use a generated one it will. The app is nice. You can see who is coming in and out and when. You can also unlock your door from your phone which is nice. It was worth the money

Una tienda 100% fiable. El producto llegó muy rápido y muy bien envuelto. Es un producto de muy alta calidad en los materiales. Finalmente no era compatible con mi cerradura, pero el servicio de atencion al cliente me ayudó mucho en todo el proceso de devolución.

Very good quality lock using it for a month without any issues. Easy to setup and fit in existing lock hole.

Lo instalé hace unos 3 meses y va muy bien. Es estético y sólido, tiene múltiples alternativas de uso y todo funciona bien. El inconveniente es que algunas de las funciones de la app solo funcionan por bluetooth y no por wifi. Por ejemplo, algunas configuraciones de las contraseñas y la comprobación de uso. La conexión bluetooth solo actúa a muy poca distancia del dispositivo, de modo que no puedo usar esas funciones cuando quiero controlarlo desde otra ubicación. Un segundo inconveniente es que el que recibà no era del color solicitado. No lo pude cambiar porque no podÃa esperar. De todos modos lo recomendarÃa a quienes lo del bluetooth no les suponga un problema.
